获取引用方法的程序集名称

Question

使用Roslyn中的SemanticModel有一种方法来获取引用方法的程序集名称吗？

var refMethod = string.Empty;
var refClass = string.Empty;
var refDocument = string.Empty;
if (location.Document.TryGetSemanticModel(out var referenceSemanticModel))
{
    var enclosingSymbol = referenceSemanticModel.GetEnclosingSymbol(location.Location.SourceSpan.Start);
if (!(enclosingSymbol is null))
{                                                        
refMethod = enclosingSymbol.Name;
refClass = enclosingSymbol.ContainingType.Name;
refDocument = Path.GetFileName(location.Location.SourceTree.FilePath);

Answer 1

就在这里。我想这两行应该适用于您的代码：

var containingAssembly = enclosingSymbol.ContainingAssembly;
var containingAssemblyName = containingAssembly.Name;

ContainingAssembly具有程序集名称，位置等信息。您可以设置一个断点并进行检查。

如果它不起作用，下面是我用于相同目的的代码，它工作正常：

private void AnalyzeNode(SyntaxNodeAnalysisContext context)
{
    var invocationExpr = (InvocationExpressionSyntax)context.Node;
    var memberAccessExpr = invocationExpr.Expression as MemberAccessExpressionSyntax;
    var memberSymbol = context.SemanticModel.GetSymbolInfo(memberAccessExpr).Symbol as IMethodSymbol;
    var namespace= memberSymbol?.ContainingNamespace;
    var assemblyName = memberSymbol?.ContainingAssembly;
}
